Abstract
| The common coil configuration was one of the layouts studied as a candidate to build the required high-field magnets for future colliders, specifically FCC-hh at CERN. The design of the structure to support the large electromagnetic forces and the protection system have been identified as the main challenges. Racetrack model coils (RMC) have been used as successful tools for the R&D; of high-field superconducting accelerator mag-nets for more than a decade at CERN. In this article, a common coil magnet, named ISAAC, is designed using existing RMC coils. This approach will allow to build a common coil model magnet in a short time to validate the calculations and identify the weak points to overcome before addressing the challenge of building a 14 T common coil magnet demonstrator in CIEMAT premises. A preliminary study is carried out to compare results from common coil configuration with those obtained for the same RMC coils assembled in block configuration. More critical properties of magnetic design are discussed, and two design options are presented. Finally, the quench protection and mechanical design goals to be pursued are discussed. |
